Expand description

Extend SqliteProjectionStore with vector support

Required Methods§

Source

fn load_vector_extension(&self, path: Option<&Path>) -> Result<()>

Load the sqlite-vector extension

§Example

use azoth::prelude::*;
use azoth_vector::VectorExtension;

let db = AzothDb::open("./data")?;
db.projection().load_vector_extension(None)?;

Source

fn vector_init( &self, table: &str, column: &str, config: VectorConfig, ) -> Result<()>

Initialize a vector column

Must be called after creating the table with a BLOB column.

§Example

use azoth::prelude::*;
use azoth_vector::{VectorExtension, VectorConfig};

// Create table with BLOB column
// Initialize vector column

Source

fn has_vector_support(&self) -> bool

Check if vector extension is loaded

§Example

use azoth::prelude::*;
use azoth_vector::VectorExtension;

let db = AzothDb::open("./data")?;
if !db.projection().has_vector_support() {
    db.projection().load_vector_extension(None)?;
}
